Glass

The raw materials that are used to create glass are sand, soda ash, dolomite, limestone and sodium sulphate. All these materials need to be quarried and transported to factories where they are used to make glass. Once the glass is made that is then again transported to where it is needed. All this transport can be reduced if the factories are placed near the quarries.An advantage of the glass manufacturing processes in some cases is that the finished article is produced immediately, as opposed to the production of an intermediate product that then requires transport to another factory for conversion e.g. steel sheets made for can manufacture.
